For those of us who live and breath by our calendar, making sure that you always have access to it, is a must. Enter the CalDAV Protocol: A standardized way for different clients to access one calendar. Leopard’s (OS 10.5) iCal application has built in CalDav support, and it works great with Zimbra 5.0. Here’s a quick overview.
Although we mention iCal (because it’s the easiest to set up), this works with just about CalDAV client. If you have questions or comments, feel free to stop by the Zimbra Forums to continue the discussion.
1) Make sure that you’re running Zimbra 5.0 or higher. If you are a Zimbra user, and don’t have access to the server, then open the Web Client and type ” $set: get version ” in your search bar. This will display the Zimbra version. Anything above 5.0 will work great.
2) Open iCal.
3) Select “iCal” from the menu at the top and choose “Properties”
4) Click the “Accounts” and press the + sign
5) Give your new Calendar setup a name like “Zimbra server” or “Work Calendars”
6) Enter your username and password
7) Press the > sign and enter your server information. This is the address that you use to go to the Zimbra Web Client. If you don’t know the URL, ask your system administrator. NOTE: Only enter the domain name, ie http://mail.server.com and do not enter anything after the .com or .edu including the trailing /
Peice of cake.

I’ve found that this does work incredible well w/ the new v5.x of ZCS — but my one concern is using it to sync thru iTunes to an iPhone… is it even possible? I tend to think that the possibility exists — or should we just wait for ActiveSync and do it over the air and not even hard-sync the iPhone anymore!!

[…] (the standard .ics not the Apple program) only gets you so far. We’ve previously covered CalDav in Apple’s iCal for Mac, but where does the CalDav field stand for Windows and Linux […]

I’ve found this basically works but it is awkward. Meeting announcements come to Mail and they show up in iCal but it is not clear if I have accepted or not. I usually have to go to meeting info, scroll to bottom, select ‘Accept’ even though it already says ‘Accept’ and then press ‘Reply.’ Also I cannot accept/reject meetings from Mail but have to go to iCal.
